Plants usually cespitose, sometimes stoloniferous, nodes of the stolons
often pilose. Culms 10-75 cm, erect or depressed-decumbent; cauline
nodes glabrous or slightly pubescent. Sheaths compressed, mostly glabrous,
margins ciliate; ligules 0.2-0.4 mm; blades 4-15 cm long, 1.5-6
mm wide, flat, mostly glabrous, margins with papillose-based cilia. Panicles
terminal and axillary, 5-11 cm overall, rachises to 3 cm, with 2-7 branches; branches
2-9(12) cm, spreading or ascending. Spikelets 1.6-2.2(2.8) mm, ovoid or
ellipsoid, obtuse to acute. Upper glumes and lower lemmas scarcely
extending beyond the upper florets, 2-veined, margins sparsely pilose, apices
obtuse to subacute; upper lemmas and paleas 1.6-2.1 mm long, 0.5-0.7
mm wide. Caryopses 1.5-1.8 mm, gray. 2n = 20, 40, 80, 100.
Axonopus fissifolius is sometimes used as a lawn or pasture grass, but
it is also an invasive weedy species, often growing in moist, disturbed sites.
It is native in the southeastern United States and from central Mexico south to
Bolivia and Argentina. It has also been introduced into tropical and subtropical
regions of the Eastern Hemisphere.
